ASTM E96/E96M-2022更新了哪些具体内容？
有哪位老师知道，ASTM E96/E96M-2022相比ASTM E96/E96M-2016，更新了哪些具体内容？Changes to ASTM E96-22 ASTM E96-22 revises the previous edition of the same standard for test methods for water vapor transmission rate, which was published in 2021. The new version has undergone the following changes to keep its information current: The section covering the balance of the assembled dish mass of the apparatus was significantly expanded and restructured. The procedure for weighing the dish assembly in the desiccant method was updated. Details on plotting the weighings of the specimen at the steady state portion of the test were clarified and restructured. Millimeters of mercury (mm Hg) was removed as a unit of measurement for vapor pressure difference and saturation vapor pressure at test temperature values, which now exclusively use pascals (Pa). Any past user of this standard who is interested in all the changes made to the 2022 edition can get the ASTM E96/E96M-22 Redline Standard, which comes with both ASTM E96-22 and a version of the document that clearly marks where changes have been made. Changes to ASTM E96-21 The previous edition of this standard, ASTM E96-21, is recent enough for its users to have an interest in knowing its changes, which were numerous. The most obvious of these changes is the update to the title. ASTM E96/E96M-16 was titled, “Standard Test Methods for Water Vapor Transmission of Materials,” while ASTM E96/E96M-21 expanded its title to “Standard Test Methods For Gravimetric Determination Of Water Vapor Transmission Rate Of Materials.” The standard document contains numerous clarifications and updates throughout its text. This includes new sections on: vapor pressure difference in a common controlled atmosphere requirements for when the specimen area is larger than the mouth area testing of materials of homogenous composition and physical structure requirements for testing an additional blank specimen specimen thickness measurement warpage and breakage of the seal of the specimen to the dish during testing determination and utilization of steady state ASTM E96-21 also features a new Appendix X5, “Examples of Calculations.” Any past user of this standard who is interested in all the changes made to the 2021 edition can get the ASTM E96/E96M-21 Redline Standard, which comes with both ASTM E96-21 and a version of the document that clearly marks where changes have been made.

有ASTM E96-22吗，发我一下
论坛回复功能今天才刚恢复，之前都打不开，截止目前我也没有找到2022版本的文件。 标准我们早就有了
